Function and Role of the Washer Pump in âFrigidaire Machines
Theâ 137311900 Frigidaireâ Washer Pump is âŁa compact centrifugal drainâ pump designed⤠to â¤evacuateâ wash and rinse water from the tub into the âhousehold⤠drain. A sealed â¤electric motor⣠drives a molded impeller âthat âŁconverts torque âinto âŁflow and⣠pressure, allowing the assembly to overcome tub lift, inline âŁcheck⤠valvesand hose resistance;â the pump often includes âa â˘small â˘inletâ strainer⤠and âa thermal protector to limit motor overheating.⢠For replacement applications,â confirm â¤that â¤the mounting ear pattern, hose barb diametersand electrical connector style âmatch the machine harness and tub outlet so the pump âinstalls âwithout adapter modifications.
- Primary function:â remove water from âthe âtub âduringâ drain and some rinse/spin cycles.
- Drive characteristics: sealed motor with molded plastic impeller; torque and speed determine flow/head.
- Common failure symptoms:â humming without⤠flow, reduced flow, grinding âŁnoise,â leaks, âor intermittentâ operation.
- Compatibility checklist: mounting footprint, inlet/outlet hose fit, â¤and connector pinout.
Technicians troubleshoot â¤the unitâ by checking âfor foreign objects in the inlet,â inspecting the⣠impeller and housing for⢠cracks, â¤measuring motor winding resistanceand verifying supply voltage⤠at the harness⢠while exercising the drain â¤command. Practical âbench tests include applying appropriate mains voltage briefly to confirm rotation and flow (observe safe â¤practices)and replacingâ the pump when â˘bearings âŁareâ noisy, the âŁimpeller is broken,⢠or the motor shows â¤an open or shorted winding; these behaviors â˘indicate mechanical âor electrical âfailure that â˘cannot⢠beâ remedied by external cleaning alone.

How the 137311900 Frigidaire Washer âPump âWorks âŁInside the â¤Appliance
The⣠137311900 frigidaire âwasher Pump is anâ impeller-driven drain assembly that evacuates wash and rinse water from the tub through â˘the drain hose during drain and spin cycles. The unit consists âŁof a⢠small âelectric motor, molded plastic âhousing, an elastomeric seal where âthe motor shaft passes into the wet chamberand inlet/outlet hose connections; the impellerâ generates the flow âwhile the⢠motor provides rotational torque.â Mechanically â˘the pumpâ mounts âto the washer chassis or â˘tub with a flange or clips and connects electrically via spadeâ terminals or a multi-pinâ connector so the appliance control â¤board can energize it â¤for âtimed âdrain intervals. Verify⢠model compatibility by matching the OEM part number âand connector orientation to avoid fitment issues with hose lengths, mounting pointsor⢠electrical wiring harnesses.
- Symptoms of pump issues: humming without waterâ movement, no drain during programmed âcycles, washing machine error codes for âdrainage, âor âaudible grinding if debris âcontacts the impeller.
- Fast âdiagnostics: check for â¤foreign⢠objects in the â¤inlet,verify âcontinuity across motor terminalsâ with a multimeter,confirm 120VAC (or appliance-specific âsupply) is present âwhen control calls â¤for drain,and inspectâ seals âŁfor leaks.
- Practical replacement: remove front⤠access â¤panel, âdetach hoses, document connector positionsand test the âoldâ pump⣠off⣠the machine if⣠uncertain before installing the replacement.
Operationally the pump responds to low-voltage controlâ signals⢠only insofar⢠as the control board suppliesâ mains voltage to the motor⤠terminals;⢠no separate sensor insideâ theâ pump governs cycle â¤timing. Failures are usually mechanical (clogged impeller, worn bearings) or electrical â(open motor windings,⣠shorted windings, âŁor⢠burned brushes inâ brushedâ motors). âWhen servicing, technicians⤠should isolate⢠the washer from mains power, drain standing â˘water â˘first to reduce mess, âand inspect both the pump housing for⣠cracks and⢠the drain path (trap, hoses, standpipe) for restrictions that can mimic â¤pump â˘failure. Replacing⣠the unit⤠with a â¤correctlyâ matched 137311900 âŁassembly â¤preserves âoriginal connector layouts and hydraulic characteristics, â¤minimizing the need forâ additional âŁmodifications.

Common⤠failure â¤Symptoms âand Diagnostic âŁIndicators
The 137311900 Frigidaire Washer Pump is a compact electrically driven drain pump designed to⢠evacuate wash and rinse water through the machine’s âdrain hoseâ duringâ drain âand spin cycles. âŁIt âfunctions as⤠a centrifugal âŁimpeller⣠mounted on aâ small motor shaft; proper operation requires free⤠impeller rotation, intactâ housing sealsand correct âelectrical feed and mounting orientation. Compatibility âconsiderations include the pump’s electrical⤠connectorâ type, âinlet/outlet hose diameters, âŁand mounting tab locations – a direct-fit â¤replacement â¤will match⤠those⢠mechanical and electrical interfaces.⣠For example, â¤lint, small garmentsor⣠foreign objects trapped in the âimpeller â˘commonly produce slow drainâ symptoms âthatâ are resolved â¤either âby clearing the obstruction or replacing the pump if⤠the impeller or motor is damaged.
- No draining⣠but pump hums – indicates motor receives âvoltage but impeller is seized or â¤stripped.
- Slow⢠draining or intermittentâ performance -⤠suggests partial âblockage inâ the â¤impeller,check valve,or drain⢠hose.
- Loud grinding or rattling -â worn bearings or foreign âdebris contacting the⣠impeller; replacement is usually required.
- Water âleaking âbeneath the unit – sealâ failure âor cracked pumpâ housing leading to external leakage.
- Pump âŁdoesâ not energize and there is no voltage atâ the connector â- electrical fault upstream⢠(controller, wiringor door switch).
Diagnostic workflow combines observation⤠and âbasic electrical âchecks: verify visible foreign material, manually⤠spin theâ impeller after disconnecting âpower, âthen confirm that the⤠pump â˘receives the expected supply â¤voltage (â120 VAC in â¤standard Northâ American machines) during a drain command.⤠Measureâ motor winding continuity for an open circuit and âtest âŁfor⤠short-to-ground; a âlow-resistance continuity between motor leads with no continuity to chassis indicates â¤the âwindings âare intact, âŁwhereas an âopen winding or excessive leakage to ground indicates motor failure. âif⢠the pump hums with correct voltage â¤presentâ but the impeller⣠does not âturn, mechanical seizure or damaged impeller blades are probable causes â¤and replacement is generally the moast reliable fix; when replacing, ensure the replacementâ matchesâ electrical connector, hose⤠diameterand mountingâ orientation of the âoriginal⣠unit.
Replacement⢠Considerations, Compatibilityand âTroubleshooting Procedures
The 137311900 frigidaire Washer pump is a compact motor-impeller assembly responsible for evacuating wash and rinse âwater from the tub through⤠the drain hose. Mechanically, the unit transfers torque âfrom a small electric motor âŁto a molded impeller;⤠hydraulically, its performance depends on âimpeller condition, â¤inlet/outlet clearancesand hose diameter. Common failure modes include clogging by âsmall garments or debris, mechanical seizure from worn bearings or brokenâ impeller vanes, seal âŁfailure âŁthat causes⣠leakage into⣠the motor,â and electrical faults such as âopen windings orâ intermittent⤠brushes. Replacement pumps mustâ match âthe original pump’s mountingâ geometry, impeller orientation, âand electrical âconnector to âensureâ correct fit and drainage behavior â˘in the host âFrigidaire model.
For â˘replacement and troubleshooting, verify the âOEM part âfitment, check the pumpâ label for rated voltage andâ wiring configuration, â¤and inspect âthe physical âmatingâ interfaces (mountâ tabs, hose diametersand connector type) âbefore installation. Diagnostic steps âinclude âverifying⢠presence of supply âvoltage âat the pump connector âŁduring a drain cycle,⢠measuring⢠motor winding âŁresistance with a multimeter, checking free rotation of the âimpeller by hand after disconnecting⢠powerand clearing visible obstructions inâ the inlet or pump âŁhousing.⣠Afterâ installing a replacement,â run a â¤short drain â¤cycle and inspectâ forâ leaks and proper flow;â if the pump hums but⣠does not turn, further investigateâ motor windings â¤or seized bearings rather than replacing hoses âor âcontrol⢠electronicsâ prematurely.
- No drain but motor hums – check for âobstructions, test continuity and measure⣠voltage at⣠the âconnector.
- Leaking pumpâ housing – inspect seals and replace the pump⢠assembly⣠if housing⤠or shaft seal is compromised.
- Intermittent operationâ – verifyâ connectorâ integrity and â˘wiring âŁharness âŁcontinuityand test motor under load for heat-related âfailure.
